I have installed the latest version of xampp 1.8.1 portable version on my windows xp machine. The problem is there is already a version of app server running on my machine which is used for other pupose. I want to run both the app server and xampp portable on the same machine simultaniously.

To achieve this I have read the posts in the forum and succesfully changed the apache port number from 80 to 8080. And now apache is running on 8080 port.

Now I want to change the mysql port number from 3306 to 3307. Which files do I need to change to make this happen. I have gone through many forum posts and could not find the answer. Please help me.

unregister? I did'nt get you. I have appserver running with apache on port no 80 and mysql on 3306.

Now I want to run another instance of xampp with apache and mysql.I have changed the apache port no to 8080 in xampp con fig files and its working fine.(Now two instances of apache are running one on 80 from appserv and the other from xampp on 8080)

I want to change the port no for mysql in xampp from 3306 to 3307 so that I can run 2 instances of mysql one on 3306 from appserv and 3307 from xampp.
